When purchased was told strong rebuild with about 2K miles on it. After installing noticed it smokes a little blue at high RPMs. Looked over and found #3 cylinder has some wear near the top of the cylinder wall where the rings do run over. Not knowing if boring to 60 over would clean up I went another route not wanting any sleeves. Good oil pressure, good power, sounds nice. Has a Comp 280 cam with hydraulic flat taper lifters.
I do have a video of it running. Would make a great derby engine or something like that, just not what I am wanting at this time.
Message me with any questions. Will come as shown other than no flywheel and water pump.
